pkgsrc-rs - A Rust interface to pkg_install packages and database

This is being developed alongside pm, a Rust implementation of a pkgsrc package manager. Anything that handles lower level pkg_install routines will be placed here.

Testing notes

Generate list of dependency matches.

bash sqlite3 /var/db/pkgin/pkgin.db 'SELECT remote_deps_dewey FROM remote_deps' | sort | uniq > pkgdeps.txt

Generate list of package names

bash sqlite3 /var/db/pkgin/pkgin.db 'SELECT fullpkgname FROM remote_pkg' >pkgnames.txt

Implement the following algorithm in both C and Rust and compare output

bash while read pattern; do while read pkg; do pkg_match "${pattern}" "${pkg}" printf "%s\t%s\t%s", ${pattern}, ${pkg}, $? >> outfile done < pkgnames.txt done < pkgdeps.txt

As an added bonus, the C version took 55 seconds to generate 158,916,879 matches, whilst the Rust version took 42 seconds.
